0.000What This Code Means
Melanoma of the upper eyelid of the right eye, including the corner of the eye (canthus).
Coding Tips
- •The fifth digit '1' specifies right upper eyelid; ensure documentation confirms this specific location
- •Canthus refers to the corner where upper and lower eyelids meet; document if involved
Clinical Significance
Malignant melanoma of the right upper eyelid, including the canthus. This is the most specific code for this location and laterality. Upper eyelid melanomas have distinct surgical considerations because of proximity to the brow and lacrimal apparatus. Wide excision with reconstruction and sentinel lymph node biopsy of parotid and cervical basins are typical.
Documentation Requirements
- ✓Right side and upper eyelid explicitly documented
- ✓Breslow depth (millimeters of invasion)
- ✓Ulceration status
- ✓Whether the medial or lateral canthus is involved
- ✓Sentinel lymph node biopsy results
- ✓AJCC staging and mitotic rate
